Not able to connect anymore

I have been using enigma for a while with my VU+ Duo2 tuner. When I changed to a Dreambox 7020HDv2 I am not able to connect Enigma TV to my new Dreamboox. It is the same ip adress, same router and ethernet cable. Whatever I am trying I get this message:
"The tool cannont connect to the your receiver, please verify your connection settings"
I can connect with WebInterface, Telnet and FTP - but EnigmaTV NO
Updated to version 2004 - I also have the debug version installed with the same error. Have deleted all config files - but no
